A class D amplifier 100 has an integrator 10, a comparator 12, and a frequency compensation and gain control (FCGC) circuit 40. The FCGC circuit 40 senses the output and reduces the gain in order to keep the sampling frequency high enough to avoid audio artifacts.

Un amplificador 100 de la clase D tiene un integrador 10, un comparador 12, y un circuito 40 del control de la remuneraciĆ³n y del aumento de la frecuencia (FCGC). El circuito 40 de FCGC detecta la salida y reduce el aumento para guardar la frecuencia de muestreo arriba bastante para evitar los artefactos audio.
